Diamond Machining Technology (DMT) 8-in. DuoSharp Plus Bench Stone Whetstone Extra Fine/Fine Grit Diamond Sharpening Stone with Base (WM8EF-WB)

What do I like so much about this sharpening stone? I have tried all of the different whetstones out there, as well as sharpening stones, honing rods, etc.. I always sharpen my own tools and also my own chef's knives as well as a few camping knives. This is the best diamond sharpening "stone" on the market. For example I must have used my first one for over four years and just a month ago bought this one to replace it! And I use this a lot. I do a lot of high end residential installation, so all of my equipment, as in cutting pliers, pocket knives, (we uncrate and unwrap tons of expensive art pieces) razor knives, and I even sharpen my awls. With this diamond bench stone I can get the edge back on my pocket knife to razor sharp in about 5 minutes. One of my installers gets a kick shaving in front of the crew with one of my pocket knives that has an exceptionally good blade right after I sharpen it. I also cook a lot and I always sharpen my cooking knife set either before of after I used them. Depends on how many times I have used them that month. This bench stone does such a great job that I really have to remind myself not to put to much pressure on the edge of the blade as I stroke it along the bench stone. Sooo... If you get one of these you will know what I am trying to describe in a minute. This bench stone is so useful, it works so well, and also so quickly that it is just a pleasure to sit down and use it. And don't think that just because it has some diamond abrasive materials that it will ruin your blades. It is quite the opposite. The fact that you can really only use light strokes with very little pressure allows your blades a much longer "use" time. By like double or triple its usual lifetime. And that is because you aren't grinding down the overall steel as much as you would using anything else every time you use it! If you ever have your tools or knives sharpened by grinding, that process, although it gives you an incredibly sharp edge, also reduces the width of your blade each time it has been sharpened by grinding. And you can get a very very similar incredibly sharp edge just using this bench stone without losing any of your steel. So I really love this bench stone. I couldn't run my business without it. I really recommend trying this one out. And I am probably understating how long I had it before I replaced it. I probably used it for closer to six years now that I am writing and thinking about it.

I own a lot of expensive knives: Kitchen and hunting. Knives that were razor sharp when new and over time they were anything but. I have tried Arkansas stones, ceramic rods, and many other sharpening systems and tools. Nothing is a good as the DMT bench. One side is red and one is green. The red takes a not sharp (but not abused) blade and hones it first. Maybe 5 to 6 passes per side. Then you move to the green to take the sharpening to a new level with 3-5 passes per side. Almost like new. A dull knife takes maybe 3 minutes to sharpen. An "almost" sharp refresh, using only the green side, takes about a minute. I can do the whole kitchen rack of 15 knives (refresh only) in 30 minutes. Success for me relied on two things: the correct angle and the correct pressure per pass. I used the recommended "lay two quarters on top of one another" in the manual to get the feel of the angle. Once I got the feel I don't use them anymore. Initially I was putting about the amount of force I used to use with sharpening stones. It was too much. Now I used just enough pressure to keep the knife on the surface (either red or green). And by that I mean almost no pressure. If you have a kitchen scale I find about 1-2 oz of pressure works best for me. Any more than that and I just hone off good steel. It seems I use less pressure each time and the diamond surface works perfectly. I expect to get even better and the knives even sharper. This sharpening system is definitely worth the price. Highly recommended. Use it for two weeks and relegate your old systems to your favorite charitable donation site. Note: I also use the DMT 12" Diamond Steel between sharpenings. (see my separate review). I use it while paring and carving AND to sharpen my serated bread knife. I can now slice warm bread again. Update 2/3/13 Tried the fine/extra fine stones on three no longer used knives. I suspect we stopped using them because they were so dull. The fine/extra fine really couldn't set a new edge (they were too far gone). So I picked up up a second stone (Extra Course (black) / Course (blue)to use with my original base. I went to work on the knives starting with the extra coarse to see if I could resurrect my lost causes. Six passes on each side first with the black and then six passes per side with the blue and a new edge was set (1 knife needed 4 more each side with the black). Now all three are in the every-other-week rotation for fine tuning edges. Maybe I could have worked at using the fine/extra fine (aka red and green) but I decided to do it right. Plus I intend to begin working on my shop tools (planes, chisels, etc) and these will get work there. Granted these are not inexpensive tools. But, both bench stones and the base set me back roughly the cost of just one of my knives: a 10" Global chef.

Comprem, será o melhor produto que já imaginaram possuir para afiar suas facas ou equipamentos. É o segundo que compro. Agora tenho às granulometrias que necessitava.

Excelente Herramienta

Eccezionale!!! Usata su un coltello pieno di cippature….. portate via tutte in 5 minuti dopodiché sono andato con un’altra pietra più fine per fare di nuovo il filo tagliente. Ma per sgrossare e correggere la geometria della lama da piccoli e grandi problemi è fantastica!!!! Unica osservazione che la parte a grana grossa quindi quella nera è veramente molto abrasiva…. Quindi prestare la massima attenzione se non si vuole fare poi un danno irrimediabile

J'apprécie déjà le format poche DMT (4 références) particulièrement adapté en extérieur ou déplacement. Je me suis fait plaisir en achetant ce Duosharp DMT (fin, extra fin) vraiment stable - et surtout très grand - pour travailler confortablement et en sécurité. C'est cher, mais c'est vraiment TOP et durable en terme de qualité (garantie 25 ans). A noter, le prix vraiment intéressant sur cette référence, livraison comprise.

Love how fast it removes metal
